Laptop Repaste

[JJeremie11]

I'm planning to repaste my laptop (specs below) as it runs a little too hot for my liking. Running at 90C and above even at idle. However I'm unsure of what to do on a particular aspect of the process. From videos and images (also below) my laptop uses thermal paste on components around the CPU and GPU. I've got a pretty good grasp of applying CPU and GPU thermal paste so that isn't an issue for me. To the point, for the components around both chips would it be sensible to replace the paste with a suitable thermal pad? If not what thermal paste would be appropriate for those components?

 

Laptop Specs:

ASUS ROG Zephryus M GA502DU

Ryzen 7 3750H

GTX 1660 TI Max-Q

16GB RAM

Generally, applying thermal pads on the chips surrounding the CPU/GPU is okay but that is usually done on desktop components that have imperfect heatsink plates so they require thermal pads as the thermal paste wouldn't even make contact, but this seems to be designed to make contact with the surrounding chips so that must have been done for a reason as thermal paste is much better, and considering laptops have inadequate heatsinks it's better to apply thermal paste if you have the option to do so.

 

As for which type of thermal paste, you need a non-electrically-conductive one like MX-4 so if it ever spills out the sides it doesn't short the PCB.
